how it works
Apple Watch + Oura Merge: Actionable Insights in Hammr
Per-metric merge settings combine Apple Watch and Oura sleep data into one Readiness signal — then change macros and training volume.
Two wearables, one decision
Some athletes wear Apple Watch all day and Oura at night. Hammr lets you choose per-metric merge preferences — prefer Oura sleep, Watch HRV, and so on — instead of fighting duplicate Health entries.
From raw data to daily plan
Recovery score from overnight physiology: HRV, RHR, sleep, respiratory rate, wrist temperature
Readiness composite adds training load, check-in, and nutrition adherence
Mental Stress for psychological load with workouts filtered out
Sleep score vs personal sleep need
Premium Adaptive Decision
Once per day, Hammr locks an Adaptive Decision that adjusts calorie and macro targets plus workout volume prefills. The merge you configure directly affects that decision.
Dashboards inside Hammr
Apple Health and Oura dashboards show day-by-day activity rings, recent workouts, and vitals summaries — so you do not bounce between vendor apps for context.
Who this is for
Oura-first sleepers who train with Watch, or anyone tired of ghost duplicate metrics in Health. Hammr is iOS only and built for one closed loop on one Home screen.
